GEORGE B. TAYLOR, OF NEW BRUNSWICK, NEW JERSEY.

FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 236,279, dated January 4, 1881.

' Application filed May 1VB,1880. (N0 model.) I

To all whom it may concern:

Be it known that I, GEORGE B. TAYLOR, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new and useful Improvement in Feed-Water Heaters, of which the following is a specification.

Figure 1 is a sectional plan view of the improvement. Fig. 2 is a sectional end elevation taken through the line 00 m, Fig. 1. Fig. 3 is a plan view of one of the heating-chambers, the inner plate being removed.

Similar letters of reference indicate corresponding parts.

The object of this invention is to heat the feed-Water before it is introduced into the boiler of a locomotive or other engine by means of the heated products of combustion as they pass through the smoke-box on their way to the smoke-stack.

The invention consists in a heating-chamber formed of two plates attached to opposite sides of a frame, and having its interior divided into a zigzag form by strips extending alternately from the top and bottom to the bottom and top, as hereinafter described.

Arepresents the flue-plate, and B the smokebox, of a steam-boiler.

O are the heating-chambers, which are formed by securing plates to the outer and inner sides of frames. Theheating-chambers (l are curved to correspond with the curvature of the sides of the smoke-box B, and are secured to the shell of the said smoke-box by bolts, so as to leave a narrow space between them and the said shell for the passage of the heated products ofcombustion. The interior of the heating-chambers G is divided up into a long narrow channel by strips of angle-iron D secured between the plates of the said chambers and extending alternately from the lower nearly to the upper bar of the frame of the said chambers, and from the upper nearly to the lower bar, as shown in Fig. 3, thus forming a narrow zigzag channel, through which the water passes in a small stream on its way to the boiler, and in which it is constantly receiving heat from the plates of the chambers G.

E is the pipe leading from the pump or water-reservoir, and which passes in through the the zigzag channel of the first heating-chamber the water passes through the connectingpipe F into the forward end of the zigzag channel of the other chamber 0 D, where it is further heated. From the rear end of the zigzag channel of the second heating-chamber O D the water passes through the pipe G into the boiler.

The pipe G, near its rear end, where it entore the .boiler, is provided with a check-valve, H, to prevent the water in the boiler from being forced back through the pipe G into the heating-chambers.

The inlet-pipe E, near the point where it enters the heating-chambers C D, is provided with a check-valve, I, to prevent the waterin the heating-chambers from being forced or drawn back into the pipe E.

In the lower parts of the division-strips D, that extend down to the bottom of the heating-chambers G, are formed small holes, as shown in Fig. 2, to allow the water in the heating-chamber to have a circulation when the pump is not working. With this construe tion the feed-water is heated by the products ofcombustion as they pass through the smokebox B on their way to the smoke-stack, thus utilizing heat that would otherwise pass off into the air and be wasted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a feed-water heater for steam-boilers, the heating-chamber 0, formed of two plates attached to the opposite sides of a frame, and having its interior divided into a zigzag chamber by the division-strips D, extending alternately from the top and bottom of the chamber nearly to its bottom and top, substantially as herein shown and described, whereby the water is made to pass through the heatingchamber in a small stream, as set forth.

GEORGE B. TAYLOR.
